SPIRAC

SPIROLIFT® Vertical Shaftless Spiral Conveying Technology

SPIROLIFT® Vertical Shaftless Spiral Conveying Technology

SPIRAC is the global leader in vertical sludge conveying with hundreds of SPIROLIFT®  installations worldwide. This proven technology offers significant cost and operational advantage over alternate methods of sludge elevation and transport.

SPIROLIFT® vertical conveyors feature an octagonal trough and liner. The breaks in the liner provide a resistance point which helps to prevent slippery materials from forming a rotating plug, thereby encouraging the material to move vertically

Technical details

• Shaftless spiral:The shaftless spiral allows higher filling rates and lower RPMs resulting in less wear and consequently less maintenance and down time. Although the spirals can be made out of many different materials, the primary material is a special steel from Sweden which has mechanical properties that give the SPIRAC spiral a very high tensile strength. SPIRAC shaftless spiral conveyors are designed for the transport of otherwise difficult to handle materials, such as municipal dewatered sludge, wastewater screenings, grit, industrial sludges and other sticky, viscous, stringy materials.
• No intermediate or end bearings:Not having intermediate and end bearings allows a comparative reduction in major maintenance work. It also allows efficient and direct transfer – horizontal, inclined or vertical – into another conveyor.
• Liners: SPIRAC’s proprietary liner, DURAFLO® SPX, is designed specifically to ensure long life. The DURAFLO® SPX liner has a built-in wear indicator with a snap-in, snap-out feature enabling easy replacement.
• Totally enclosed troughs: SPIRAC conveyors are totally enclosed. There is no spillage of the material being conveyed and odours are completely contained.
• Direct drive: SPIRAC’s direct-drive design allows a clean and efficient transmission without the maintenance required by belt and chain drives
